I want to buy myself a Canon 70-200 f/2.8L (dunno if Mk1 is enough or will got for Mk2 yet), but the bitch costs $$.

I have an older Sigma 18-250mm f/3.5-6.3 lying around that I could sell for about 250 bucks, then get a used 70-200 f/2.8L for $800-1400.

You think it's a good trade-off? I barely use the Sigma because it frankly sucks, but it's the only wide-angle I have. I rarely shoot it but you never know.
Still, I could get a 24mm pancake for about 150 bucks and still have 50 towards my new Canon zoomy.

It's just that I feel that the savings in the end are minuscule, and maybe I should just get shooting with my 18-250 sigma. I'm not printing my photos or anything, so at screen size it should be perfectly fine.

Yet I look at my photos and see that slight CA and I suffer internally.

I dunno why I post, any experiences like this? I imagine it's a common problem. Just nobody IRL to talk to about this.

Pic related. Taken with the sigma. It's sized down, but the resolution still sucks ass, I think
